how to do research

——reading after a science paper

these days i am busy preparing my dissertation which is about web usage mining . i read some english papers and learnt much from them . and now i want to say something about a paper titled “web usage mining：discovery and applications of usage patterns from web data”.

this is the first english paper i read about dissertation and gave me great help .

this paper is a review about web usage mining. it introduced web usage mining in detail . although it is a little old for it was published in its contents are very useful today . it is organized according to the sequence of web usage mining and the six main parts are introduction which tells me what is web usage mining the sources and abstraction of web data the three steps of web usage mining taxonomy and project survey websift overview privacy issues . the third and fourth parts are most important . it had a list of existing project about web usage mining which i saw many times in other papers but this paper is the one creating this list . besides it has been referred for more then twenty times . as we all know that the higher the referred number is the more important the paper is so i consider this paper to be an important and successful one in this region.

in my opinion the success of this paper dues to three reasons . the first reason is the profound computer knowledge owned by the authors . web usage mining relates to many subjects such as artificial intelligence ontology semantic analysis but the most basic knowledge is computer science . the four authors are all professors of department of computer science and engineering in university of minnesota . for myself i am not major in computer science and i am not very good at computers so i feel a little difficult to understand technologies used in this region.

second they had read a large number of papers before they wrote this paper . there are fifty nine references listed after main contents . “stand on the shoulders of giants” this sentence tell us a truth : one can never successful all by oneself . and what’s more learn from others can save a lot of time and energy especially for us new learner . how to learn from others is a skill all of us should master but learning doesn’t mean copy or plagiary . other people’s knowledge and production is just our foundation upon this foundation we must have our own thoughts and creation. there are many remarks in this paper where referred other’s production.

third the authors had the experience of developing a web usage mining project . they don’t just engage in idle theorizing so their comprehension on this issue is greatly profound. they know what we may meet in a real project development and they know how to resolve them . after reading this paper i also read some other papers written in chinese . some of them are not based on real project and can not give useful resolution . websift is the name of system they developed which can be used to data mining and analysis .

i wrote this article not only because it gave me much help in preparing my dissertation but also because it tells me how to study and how to do research . honesty and preciseness are two essential making a researcher must have . hard-working is the necessary condition leading to success . this is just the beginning of my dissertation i should learn from these four authors both their knowledge and their attitude to study.

大学英语口语对话话题作文【二】

我有一个文具盒，里面住着铅笔、橡皮、格尺和钢笔。它们每天都生活得快快乐乐，可是有一天，它们竟然吵起来了。

铅笔弟弟说：“主人最喜欢我！他不管是写生字，还是预习，我都在为他服务。你们几个谁敢跟我比？”“不要吹牛了，小细棒子！”橡皮妹妹生气了。“你怎么敢和我相提并论！有一次，主人写错了好几个字，翻来覆去才把我找到。要不然，主人就不能改写了！”“闭嘴！”格尺姐姐怒目圆睁，恶狠狠的说。她把眼睛瞪的大大的。“我的身体直直的，用来连线和画图！再看你们几个，谁的身体直！”“停！”钢笔哥哥也一副怒火冲天的样子！“我用来写作文和考词，而且，我没有缺点！你看你们，铅笔容易断，橡皮黑漆漆，格尺扁又薄。谁都有缺点！”

它们吵得不可开交的时候，文具盒爷爷说:“孩子们，你们都是主人的好帮手，你们都很重要。只要你们齐心协力，就可以帮助主人取得更大的进步。”

顷刻间，铅笔、橡皮、格尺和钢笔都惭愧地低下了头。
